I remember the RCA BTA-1R quite fondly as it was the backup at WMMM in Westport, CT. The main transmitter, a Harris MW-1 always reminded me of an overgrown refrigerator, looks wise.

While both transmitters operated well there was nothing more frustrating with my high voltage “buddy” who accompanied me during transmitter maintenance would hit the crystal switches on the RCA to pop it into “Conelrad” mode. There was nothing more frustrating than having to open the box to manually reset the latching relay when he decided to play this little prank on me.

Those classic radio broadcast transmitters sure look neat,…and it’s nice to know some are still in use! I like the looks of the RCA units,and though they’re not pictured,…a few of the old Collins and Continental units as well. Seen photos of those on another radio related site,…www.oldradio.com,I think! Another neat looking transmitter is the 50HG-2 Westinghouse transmitter
featured on the Jim Hawkins Radio and Broadcast technology website for WOWO AM 1190!

Off-topic: Sorry, Paul. I lost your e-mail and wanted to let you know I’ve transferred my domain for “Site 2241” on your blog roll to Namecheap. The URL is now just “www.site2241.net”.
BTW, I loved your post on the Titanic!

Hi everyone. Iam based in Australia. I am seeking some information on a radio dation that has in use a Harris MW-50-C using 4CX-35000-C power tubes. I am truing to get hold of a set of photographs of the transmitter both inside and out, including power supply and R.F. units. Any help appreciated.

David, I’ll check around and see, many of that model transmitter has been retired. I worked on a couple of MW-50A and B transmitters over the years. They have issues with the solid state damper diodes going bad. I believe those parts are no longer available.

Thanks Paul. Any help appreciated. If you or anyone else here knows where I can get my hands on a 4CX35000C tube, please let me know. I want one for a display piece. Happy to pay shipping costs to Australia. 73’s. David………….davidbarneveld@bigpond.com

Also seeking an “AmpliPhase” nameplate from the big 50kw Ampliphase transmitter from back in the day. If anybody knows anybody with recently decommission RCA transmitters that fall in the BTA era, please let me know, as I am working on a special project for a friend with cancer, and trying to build familiar surroundings as well as get his stories written down so a documentary and perhaps even a feature film about AM radio’s glory days can be told.
